Protein Structure

UniProt Annotation

Function

Glycosyltransferase required for the biosynthesis of heparan-sulfate. The EXT1/EXT2 complex possesses substantially higher glycosyltransferase activity than EXT1 or EXT2 alone.

Subcellular Localization

Endoplasmic reticulum membrane; Single-pass type II membrane protein. Golgi apparatus membrane; Single-pass type II membrane protein. Note=The EXT1/EXT2 complex is localized in the Golgi apparatus.

Disease Associations

Tissue Specificity

Expressed in maturing chondrocytes.
